    Abstract: A wireless LAN system is provided at its access points with structured data indicating resources, connected and independent (e.g. vending machine) in the connect range of the respective access point. Guest clients, upon connecting, may download "greeting" logic to receive and display the structured data to allow the guest to be quickly at home and productive in an unfamiliar setting.

    Abstract: In accordance with the preferred embodiment, an access point provides dynami c load balancing of network bandwidth between access points within the 802.11 wireless LAN. The access point uses the RTS/CTS protocol to reduce the bandwidth available to a single device using an excessive amount of network bandwidth. The access point places a device that has been monopolizing a network channel on a Restricted List, and regulates bandwidth on the network by not returning a CTS to any client on the Restricted List. When the client 's network usage drops below a policy driven threshold set by the number of network users, the client is removed from the list and the access point will respond to a RTS from the client with a CTS.

    Abstract: A wireless network access point is described which provides the resources of a backbone network to wireless clients. The access point is able to detect a degraded condition on the backbone network. Upon detecting the degraded condition, the access point transmits or broadcasts a reassociation request to one or more clients associated with the access point. In addition, the rate at which new associations are made is halted or reduced during the degraded backbone condition. In one embodiment, the association rate is reduced by increasing the interval between beacons transmitted by the access point which identify the access to the backbone network.

    Abstract: Apparatus for assigning addresses to devices connected to an SCSI bus (10). A second configure bus (15) interconnects address assignable devices on the SCSI bus. The assignable devices may be used in a mixed system where some devices have fixed non-assignable addresses. The master device in the SCSI bus transmits configuration commands over the configuration bus and addresses for assignment over the SCSI bus. Acknowledgements are received back from a device which has accepted an address. Once configured with an address, the device propagates subsequent configuration commands to an adjacent device.
